Thunderbird Community Forum

Hi community,

I want to have the same font and font-size in:

• my HTML message body text
• my signature.html file

so I can send consistent and nice-looking e-mails, like you would expect.

Here are my current settings:

• Settings > General > Language & Fonts > Fonts >
  • Default font: Arial
  • Size: 12
  • Advanced: For both "Latin" and "Other Writing Systems" I have the settings you can see in the attached screenshots.

I heard that these settings are for personal viewing.

• Settings > Composition > HTML Style >
  • Font: Arial
  • Size: Medium

I heard that these settings are for viewing by recipients.

The first line of my signature.html file looks like this: div style="font-family: 'Arial'; color: #222; line-height: 1.0; font-size: 14px;"

There is always a slight font size mismatch of the message text with my signature.

I unsuccesfully tried tweaking the html font size values in px or pt to match the given size in Settings > Composition > HTML Style for Medium or Large.

It seems that the available font size granularity of Medium or Large just does not match corresponding pixel or point values?

I would be extremely grateful if someone can guide me on how to achieve this!

If there is no valid solution for this problem, I'm happy to open/report an issue on this.

Thank you and have a wonderful day

I have multiple email adresses for different purposes, but all of the incoming emails are sent to the Local Folders inbox, where I have separate folders to save emails for the each purpose. I am able to manually sort the folders in the order that I prefer, however each time I shut down Thunderbird and then restart it, the folders end up in seemingly different random order each time. Is there a way to ensure the manually sorted order of the folders does not change?

My windows 10 machine died on me recently, but I was able to recover all my Thunderbird Email files from the old hard drive. However, the Thunderbird settings I was using under Windows 10 did not transfer over to the new machine and there is one particular issue which is driving me crazy and I don't know how to fix:

Basically, on my previous machine I frequently filtered my emails using the threaded option based on the Subject field. However, under Windows 10 the filter I was using would ignore the "Re:" in the subject line of such threads and so every message in the thread was displayed as if the various instances of "Re:" simply weren't there. However, on my new machine Thunderbird threads messages as if each instance of "Re:" represents a new thread! How do I fix this?

I used to just have my Canon TS6350 do my printing. Great. Now Thunderbird seems to have taken over my choice of how I print for a long while and it's driving me nuts. It is a dreadful system. I have searched settings to no avail. Can someone advise a Geri Brit of 82 how to deal with the problem Thank you very much Kind regards Alan Jones

Hi, while migrating to linux mint, I had to configure my multiple mailboxes at the new laptop and OS in TB. TB under linux looks very similar to TB under W10, but not 1-on-1. I use POP3. ver. 140.10.1esr (64-bits) Mozilla Thunderbird Flatpak en-USthunderbird-flatpak - 1.0

My internet provider (ISP) has different mailbox setttings compared to the default thunderbird settings. And I have multiple mailboxes. What really struck me was "the nuisance of hand-set values being overwritten by default settings" by TB. Working from top to bottom through the input screen, many many times these previously inserted manual settings somewhere UP, were overruled when a setting LOWER in the field was toggled. (If it was n´t so annoying you may have liked it as a variation on wack-a-mole. ) It took me hours and hours to find out where things went wrong, and this glitch resulted in hours and hours over and over checking and checking. Also, what does not help, is the error message by TB, when the mailbox settings test is not succesfull. It is just a blank message, without a discription of the error.

- 1 Please make manual input overriding/priority to default settings, *especially* when entered in the logical following order of the inputfields in the screen. Dont mess with the lines higher up! Input in a field lower in the screen, may NOT toggle a field to default settings higher up in the screen!!! - 2 I noticed at one instance when the test was succesfull and the mailbox filled with downloaded mails, but the setting for SMTP was not right (test passed okay) and the message would not sent. There was no error message on the configuration of the SMTP, and there was no error messae when sending. Finally it appeared the port was not in the right value. Also, I expected the pop-up window to 'insert the sending password', but that window did not appear, TB did not get tot that part of the code? -3 Ad a short clarification to the 'unsuccesfull test'-message for mailbox configuration, for trouble shooting purposes.

Thank you in advance.

For the last 2 months I have been working to configure Thunderbird to fully replace my Gmail UI usage after their recent change to workspace options and using data to train gemini. When you deactivate those gmail features the first thing you lose are tabs for your Inbox, your Updates and your Promotions.

So far I have used tags, ThunderAI, Ollama and a locally hosted LLM to replicate the sorting of my inbox, but now I would like to be able to configure the Thunderbird UI to allow separate tabs in the menu bar for different folders, in this case Inbox, Updates and Promotions. With Inbox still being the gmail hosted main inbox and Updates and Promotions now being local folders stored in my local thunderbird installation.

Can the Thunderbird UI be configured to display folders as tabs as a default setting? I tried the "folder selection" button under customize on the toolbar but that just gives me a drop down, which is not what I want.

Thunderbird for Linux Mintmint-001 - 1.0

I run two browsers on Linux Mint 22.3

Librewolf and Waterfox.

I prefer Waterfox. It is set as default in its own settings

I open preferred application in system settings and choose Waterfox as preferred WEB. Thunderbird is preferred as MAIL I click on an email, waterfox promptly opens my 4 home pages....not the email I return to preferred applications and choose Librewolf instead of waterfox, click on the email again, and it promptly opens the email.

Waterfox has been set as the default browser. I am looking for a way to set Thunderbird to open emails with waterfox......I cannot find such a setting in Thunderbird.

I searched and found this : Make sure to check the settings in both Thunderbird and your operating system to ensure Waterfox is selected as the default for opening links.

Is there a way to do this in Thunderbirds settings?....It does not make sense that there would be, becasue Librewolf opens the email anyway....

1. I am getting Mozilla Thunderbird ESR notices pop up when I log on to my PC (W11). I checked my Thunderbird version and I have 146.0.1 and I am on the release channel so why am I getting these notices ? 2. Recently I noticed that when I try to move e-mail messages to a specific folder, I right click on the message and get the prompt Move To and then Recent Destinations where the problem exists. The list of Recent Destinations used to be in alphabetical order and now it is sorted by most recent destination time. This slows me down considerably. Please revert. Thanks !!

When using message filters "Run Now" is often greyed out after running a filter and remains greyed out after the filter has completed filtering. (Hung up?) This does not happen if the filter does not find any matching messages. Clicking on another filter and then returning to the first one returns the "Run Now" button to active (not greyed out). Not sure, but the problem might be associated with filters that copy a message file to a Local folder, or delete messages, or move messages to Trash, or all three. I'm stumped. The problem started recently and I'm not aware of any changes I made to Thunderbird.

I've got a new laptop and installed Thunderbird 150 on it. I'm so disappointed that the "Message Preview" option is missing. I really depended on that. How can I get it on this new version of Thunderbird?

I want to use Thunderbird as a one-off back up of my source email folders.

On Thunderbird PC, I have done this under Fetching mail settings with "Folder Poll Frequency" set to Never.

On Thunderbird Desktop Account settings are different. On Server settings, I have unchecked for new messages, but they are still coming through. Any advice how to stop the messages synchronising from the source email system?

I will then delete a lot of old messages on the source system, knowing they are available on Thunderbird desktop

I use the "move to" function to move emails from my Inbox to various other folders. I use the function on a daily basis. Since the last update, when I click on "Move to", the Recent list is no longer alphabetized. This is very frustrating. When will the alphabetization be returned?

I returned to London from Singapore on Tuesday 28/4. Today (4 May) I noticed that all my emails show Singapore time (BST+7) in the Inbox display in Thunderbird on my Windows laptop although the time shown for emails is correct on my mobile (iPhone).

I checked calendar in Thunderbird settings and it's set to "Use system timezone" but the time on my laptop clock is correct. The time zone in my Windows setting is also correct (London).

When I open an email it shows the correct time.

Any thoughts?

I have two Gmail accounts and one school account that uses Office 365. In the left panel where the inbox, drafts, etc. are, the Gmail accounts are listed in blue but the school account is listed in white. I can't see any reason for this difference in the accounts' settings. What does the difference indicate?

I recently moved thunderbird from my Win 7 laptop to a new laptop with Win11. All was OK for awhile. One day all of my Local Folders were no longer in alphabetical order. Some folders, like Outbox are under Local Folders. Is there a fix? Please don’t tell me to uninstall and re-install.

I would like to know if possible and or how to set up a standard "footer" if you will, to end my emails with. I am humbled to have several initials after my name, and would like to be able to have a standard button or actino to perform, to shortcut those answered emails with that sign off... Is is possible? Thank you
